The quality of workmanship keeps me calling Wolverine Heating & Cooling. Dan has done five or six projects at my home and I have been very pleased with each one. I would tell anyone to call Dan at Wolverine Heating & Cooling for any work they need done on their HVAC system. He gives me a fair price and he gets the work done quickly. He does not have to come three or four times to get one job done. I am so glad he got the furnace working again because the weather has been so cold here.
